Description

Technical Field

[0001] This invention relates to the field of tire production equipment technology, specifically to a positive and negative wrapping device and method for large tire production molding. Background Technology

[0002] Currently, the tire wrapping machine usually refers to the key part of the two-stage tire forming machine that is responsible for wrapping the tire carcass plies and positioning the tire bead. It is the core equipment in tire manufacturing, and its operational stability is directly related to the quality of tires and production efficiency.

[0003] In existing tire wrapping equipment, the actuator is exposed to the outside for extended periods during operation, making it prone to accumulating dirt, especially highly adhesive dirt. If this dirt is not removed promptly, the photoelectric sensor at the actuator may fail to detect it, leading to errors during final execution and affecting normal wrapping operations. Even if a cleaning end is provided, common cleaning ends often fail to self-clean under prolonged operation, eventually rendering the detection function ineffective. Summary of the Invention

[0015] A method for operating a forward and reverse wrapping device for large tire production molding includes the following steps:

[0016] Step 1: Start the capsule cylinder to move the connecting pipe and the mounting ring seat. The mounting ring seat then moves the reverse capsule to align with the connecting teeth on the shaft. Next, start the inflation mechanism to inflate the reverse capsule until it rotates flush with the drum. Then, begin the fabric tube bonding operation. After the fabric tube is bonded, the buckle pusher and the reverse capsule retract one finger-shaped piece position. At this point, start the finger-shaped piece cylinder to move the finger-shaped piece seat, which in turn moves the finger-shaped piece forward. Then, move the reverse capsule forward into position, and move the finger-shaped piece forward into position as well. Begin the straight wrapping and fasten the steel buckle. The coil is then moved back one position simultaneously by the buckle pusher and the finger-shaped piece. The reverse-wrapping capsule remains in place, while the finger-shaped piece moves back without opening. At this point, the reverse-wrapping capsule begins to inflate and the reverse-wrapping operation begins. The pusher ring and the curtain tube are both height-limited. The buckle pusher pushes the capsule forward, and the reverse-wrapping capsule simultaneously vents air to achieve reverse wrapping of the curtain tube. The buckle pusher then moves back, and the finger-shaped piece seat moves back, allowing the reverse-wrapping capsule to expel air and return to a flat position. The first forward and reverse wrapping is complete. The reverse-wrapping capsule is then buckled, and the finger-shaped piece and buckle pusher simultaneously return to their original positions to begin the second forward and reverse wrapping operation.

[0017] Step Two: During the forward and reverse wrapping operation, first start the single-phase motor to drive the working screw to rotate. The working screw drives the moving screw sleeve and connecting frame plate to move horizontally, which in turn drives the moving machine plate to move horizontally, and drives the fixed frame and forward and reverse wrapping mechanism to move. During the rotation of the working screw, the mounting plate drives the multi-section telescopic rod to move, and drives the connecting ring plate to move, which in turn causes the connecting long pipe to move. When the moving screw sleeve moves to the left, it squeezes the telescopic end of the multi-section telescopic rod on the left, and drives the moving piston to squeeze. This delivers the airflow generated when the multi-section telescopic rod retracts to the inside of the connecting ring plate, and then to the inside of the connecting long pipe. Finally, the airflow is sprayed out through the cleaning nozzle and sprayed to both sides of the connecting long pipe, so that the airflow comes into contact with the cleaning brush and the outside of the working screw, cleaning the cleaning brush and pre-treating the outside of the working screw.

[0018] Step 3: The connecting ring plate drives the annular plate to rotate, which in turn drives the rotating ring bar to rotate. When the rotating ring bar rotates, it drives the annular slide bar to rotate inside the mounting ring groove, improving the stability of the rotating ring bar during rotation. The annular plate drives the cleaning brush bar to rotate, causing the cleaning brush bar to contact and rub against the outside of the working screw, cleaning the working screw. The annular plate drives the movable tube and movable rod to move, and the movable rod drives the mounting ring frame and the detection elastic hook to slide inside the thread groove of the working screw, thus treating highly viscous dirt. When the detection elastic hook moves, it comes into contact with the cracks created by the working screw, causing the detection elastic hook to... When the head engages with the crack, it creates a pull that prevents the movable rod from moving further. This causes the movable tube to slide outside the movable slider and the movable rod, while simultaneously compressing the compression airbag. This forces the air inside the compression airbag into the movable rod, creating air pressure that pushes the movable sleeve downwards. During this movement, the fixed spring is compressed. Later, the compressed fixed spring drives the movable sleeve upwards to reset. When the movable sleeve reaches the bottom of the movable rod's inner cavity, it compresses the pressure sensor, triggering an alarm in the external remote control center and disconnecting the power to the single-phase motor to stop further movement.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] In the process of mobile production, this invention can perform comprehensive processing of the horizontal moving end, both deep and shallow, increasing the sufficiency of the processing and improving the accuracy of the execution end during movement. It avoids prolonged exposure of the moving end to the outside, preventing dirt from accumulating on its upper surface, especially adhesive dirt inside the factory. When this dirt adheres and is squeezed, its adhesion becomes even stronger. When the execution end comes into contact with this dirt during operation, it can easily cause the photoelectric and sensor ends to fail to detect it, leading to errors and product defects in later use. Furthermore, the invention allows the processing end to self-clean itself during the processing process, preventing it from accumulating dirt over a long period of time and affecting processing efficiency.

[0021] In the process of this invention, the external surface of the working screw is inspected by swiping. When an abnormality is detected to be obvious, it will be detected immediately and handled in a timely manner. At the same time, an alarm is triggered to notify the staff that an abnormality has occurred and needs to be dealt with immediately. When triggered, the detection end can be automatically cleaned to prevent dirt from adhering to the detection end, which would prevent it from becoming unusable later. It also prevents the working screw from being subjected to excessive torque due to continuous start-stop operation during use, which could cause cracks in the working screw that cannot be detected before the inspection time, thus creating a safety hazard at the execution end.

[0038] The specific implementation method is as follows: When gas is delivered to the inside of the connecting pipe 16 through the gas supply pipe 25, when the inverted capsule 9 expands, the internal air pressure will increase, which will push the guide ring 23 to move into a vertical state, so that the inner side of the guide ring 23 contacts and squeezes the outside of the gas supply pipe 25 to form a seal. When the air pressure continues to increase, it will push the moving ring 19 to move, and drive the mounting slider 21 to slide inside the mounting groove 20, so that the mounting slider 21 contacts the pressure touch switch 22, triggering the external control center to tell the staff that the air pressure is normal. When the alarm cannot be triggered, it indicates that the inverted capsule 9 is abnormal and needs to be checked in time.

[0039] The horizontal moving mechanism 4 also includes a single-phase motor 405 and a connecting frame plate 408. A movable through groove is provided in the middle of the bottom end of the bottom frame plate 1. The single-phase motor 405 is installed on the left side of the bottom end of the bottom frame plate 1 through a mounting seat. The left end of the working screw 401 passes through the mounting shaft seat 404 and is connected to the output shaft of the single-phase motor 405.

[0041] The specific implementation method is as follows: When performing the forward and reverse wrapping operation, first start the single-phase motor 405 to drive the working screw 401 to rotate. The working screw 401 drives the moving screw sleeve 407 and the connecting frame plate 408 to move horizontally, which in turn drives the moving machine plate 2 to move horizontally, and drives the fixed frame 3 and the forward and reverse wrapping mechanism to move. During the rotation of the working screw 401, the mounting plate 403 drives the multi-section telescopic rod 402 to move, and drives the connecting ring plate 409 to move, which in turn causes the connecting long pipe 410 to move. When the moving screw sleeve 407 moves... When moving to the left, the telescopic end of the multi-section telescopic rod 402 on the left is squeezed, which in turn drives the moving piston 406 to squeeze. The airflow generated when the multi-section telescopic rod 402 retracts is then transported to the inside of the connecting ring plate 409, and then to the inside of the connecting long pipe 410. Finally, the airflow is sprayed out through the cleaning nozzle 411 and sprayed onto both sides of the connecting long pipe 410. This causes the airflow to come into contact with the outside of the cleaning brush 504 and the working screw 401, cleaning the cleaning brush 504 and pre-treating the outside of the working screw 401.

[0043] The detection and processing mechanism 5 also includes cleaning racks 505, movable tubes 506, movable rods 507, compression airbags 508, and movable sliders 509. Several cleaning racks 505 are installed on the side of the mounting ring 501 away from the connecting frame plate 408.

Several detection elastic hooks 512 are installed at the bottom end and on both sides of the mounting ring 511.

A movable sleeve 513 is movably installed in the lower end of the inner cavity of the movable rod 507. 3. The movable sleeve 513 has a U-shaped structure. The movable sleeve 513 has connection ports 514 around its perimeter. A fixing spring 516 is installed at the bottom of the movable sleeve 513. The bottom of the fixing spring 516 is connected to the bottom of the inner cavity of the movable rod 507.

The conveying port 515 has an inclined structure. Pressure sensors are installed around the bottom of the movable sleeve 513, and the pressure sensors are electrically connected to the external control center.

[0045] The specific implementation method is as follows: The connecting ring plate 409 drives the annular plate 502 to rotate, which in turn drives the rotating ring bar 503 to rotate. When the rotating ring bar 503 rotates, it drives the annular slide bar 518 to rotate inside the mounting ring groove 517, improving the stability of the rotating ring bar 503 during rotation. The annular plate 502 drives the cleaning brush bar 504 to rotate, causing the cleaning brush bar 504 to contact and rub against the outside of the working screw 401, cleaning the working screw 401. The annular plate 502 drives the movable tube 506 and the movable rod 507 to move. The movable rod 507 drives the mounting ring frame 511 and the detection elastic hook 512 to slide inside the thread groove of the working screw 401, thus achieving the treatment of highly viscous dirt. When the detection elastic hook 512 moves, it contacts the crack created by the working screw 401, thus... This causes the detection elastic hook 512 to engage inside the crack, resulting in a pull that prevents the movable rod 507 from moving further. The movable tube 506 then slides outside the movable slider 509 and the movable rod 507, compressing the compression airbag 508 and forcing the air inside the airbag into the movable rod 507. Once compressed, air pressure is created inside the movable rod 507, pushing the movable sleeve 513 downwards. During this movement, the fixed spring 516 is compressed. Later, the compressed fixed spring 516 drives the movable sleeve 513 upwards to reset. When the movable sleeve 513 reaches the bottom of the inner cavity of the movable rod 507, it compresses the pressure sensor, triggering an alarm in the external remote control center and disconnecting the power to the single-phase motor 405 to stop the operation. Example 2

[0046] A method for operating a forward and reverse wrapping device for large tire production molding includes the following steps:

[0047] Step 1: Start the capsule cylinder 8 to move the connecting pipe 16, which in turn moves the mounting ring seat 17. The mounting ring seat 17 then moves the reverse-wrapped capsule 9 to align with the connecting teeth on the shaft. Next, start the inflation mechanism to inflate the reverse-wrapped capsule 9 until it rotates parallel to the drum. Then, begin the fabric tube bonding operation. After the fabric tube is bonded, the buckle pusher 12 and the reverse-wrapped capsule 9 retract one finger piece 10 position. At this time, start the finger piece cylinder 13 to move the finger piece seat 14, which in turn moves the finger piece 10 to extend. Then, move the reverse-wrapped capsule 9 forward to its position, and move the finger piece 10 to its position as well. Begin the forward wrapping and fasten the steel wire. Circle 15. At this time, the buckle pusher 12 and the finger-shaped piece 10 simultaneously retract one position. The reverse-wrapping capsule 9 does not retract, while the finger-shaped piece 10 retracts without opening. At this time, the reverse-wrapping capsule 9 begins to inflate and begins the reverse-wrapping operation. The pusher ring 11 limits the height, and the curtain tube also limits the height. At this time, the buckle pusher 12 pushes the bag forward, and the reverse-wrapping capsule 9 simultaneously vents air to achieve reverse-wrapping of the curtain tube. At this time, the buckle pusher 12 retracts, and the finger-shaped piece seat 14 retracts, allowing the reverse-wrapping capsule 9 to expel air and restore the reverse-wrapping capsule 9 to a flat position. The first forward and reverse wrapping is completed. At this time, the reverse-wrapping capsule 9 buckles, and the finger-shaped piece 10 and the buckle pusher 12 simultaneously retract to their original positions to enter the second forward and reverse wrapping and wait.

[0048] Step Two: During the forward and reverse wrapping operation, first start the single-phase motor 405 to drive the working screw 401 to rotate. The working screw 401 drives the moving screw sleeve 407 and the connecting frame plate 408 to move horizontally, which in turn drives the moving machine plate 2 to move horizontally, and also drives the fixed frame 3 and the forward and reverse wrapping mechanism to move. During the rotation of the working screw 401, the mounting plate 403 drives the multi-section telescopic rod 402 to move, and drives the connecting ring plate 409 to move, which in turn causes the connecting long tube 410 to move. When the moving screw sleeve 407 moves to the left... When moving, the telescopic end of the multi-section telescopic rod 402 on the left is squeezed, which in turn drives the moving piston 406 to squeeze. The airflow generated when the multi-section telescopic rod 402 retracts is then transported to the inside of the connecting ring plate 409, and then to the inside of the connecting long pipe 410. Finally, the airflow is sprayed out through the cleaning nozzle 411 and sprayed onto both sides of the connecting long pipe 410. This allows the airflow to contact the outside of the cleaning brush 504 and the working screw 401, cleaning the cleaning brush 504 and pre-treating the outside of the working screw 401.

[0049] Step 3: The connecting ring plate 409 drives the annular plate 502 to rotate, which in turn drives the rotating ring bar 503 to rotate. When the rotating ring bar 503 rotates, it drives the annular slide bar 518 to rotate inside the mounting ring groove 517, improving the stability of the rotating ring bar 503 during rotation. The annular plate 502 drives the cleaning brush bar 504 to rotate, causing the cleaning brush bar 504 to come into contact with the outside of the working screw 401 and rub against it, cleaning the working screw 401. The annular plate 502 drives the movable tube 506 and the movable rod 507 to move. The movable rod 507 drives the mounting ring frame 511 and the detection elastic hook 512 to slide inside the thread groove of the working screw 401, thus treating the more viscous dirt. When the detection elastic hook 512 moves, it comes into contact with the cracks created by the working screw 401, which will cause... When the elastic hook 512 engages inside the crack, it pulls, preventing the movable rod 507 from moving further. The movable tube 506 slides outside the movable slider 509 and the movable rod 507, compressing the compression airbag 508 and forcing the air inside the airbag into the movable rod 507. This creates air pressure inside the movable rod 507, pushing the movable sleeve 513 downwards. During this movement, it compresses the fixed spring 516. Later, the compressed fixed spring 516 drives the movable sleeve 513 upwards to reset. When the movable sleeve 513 reaches the bottom of the inner cavity of the movable rod 507, it compresses the pressure sensor, triggering an alarm in the external remote control center and disconnecting the power to the single-phase motor 405 to stop further movement.

A method for operating a forward and reverse wrapping device for large tire production molding, characterized in that: The operating method of the forward and reverse wrapping device is applicable to the forward and reverse wrapping device for large tire production molding as described in any one of claims 1-6, and includes the following steps: Step 1: Start the capsule cylinder (8) to move the connecting pipe (16) and the mounting ring seat (17). The mounting ring seat (17) moves the reverse capsule (9) to align with the connecting teeth on the shaft. Then, start the inflation mechanism to inflate the reverse capsule (9) and rotate it parallel to the drum. Then, perform the bonding operation of the curtain tube. After the curtain tube is bonded, the buckle push plate (12) and the reverse capsule (9) move out one finger piece (10) position. At this time, start the finger piece cylinder (13) to move the finger piece seat (14), which moves the finger piece (10) to extend. Then, move the reverse capsule (9) forward to its position and move the finger piece (10) to its position. Start the forward bonding and fasten the wire ring (8). 15) At this time, the buckle push plate (12) and the finger piece (10) retract to one position at the same time. The reverse-wrapping capsule (9) does not retract, the finger piece (10) retracts and does not open. At this time, the reverse-wrapping capsule (9) begins to inflate and begins the reverse-wrapping operation. The push ring (11) limits the height, and the curtain tube limits the height. At this time, the buckle push plate (12) pushes the bag forward, and the reverse-wrapping capsule (9) simultaneously vents air to achieve the reverse-wrapping of the curtain tube. At this time, the buckle push plate (12) retracts, the finger piece seat (14) retracts, allowing the reverse-wrapping capsule (9) to expel air and restore the reverse-wrapping capsule (9) to flatness. The first positive and negative wrapping is completed. At this time, the reverse-wrapping capsule (9) buckles, and the finger piece (10) and the buckle push plate (12) simultaneously retract to the original position to enter the second positive and negative wrapping and wait. Step 2: When performing the forward and reverse wrapping operation, first start the single-phase motor (405) to drive the working screw (401) to rotate. The working screw (401) drives the moving screw sleeve (407) and the connecting frame plate (408) to move horizontally, which in turn drives the moving machine plate (2) to move horizontally, and drives the fixed frame (3) and the forward and reverse wrapping mechanism to move. During the rotation of the working screw (401), the mounting plate (403) drives the multi-section telescopic rod (402) to move, and drives the connecting ring plate (409) to move, which in turn causes the connecting long pipe (410) to move. When the moving screw sleeve (407) moves to the left... When moving to the side, the telescopic end of the multi-section telescopic rod (402) on the left side is squeezed, and the moving piston (406) is squeezed. The airflow generated when the multi-section telescopic rod (402) retracts is delivered to the inside of the connecting ring plate (409), and then to the inside of the connecting long pipe (410). Finally, the airflow is sprayed out through the cleaning nozzle (411) and sprayed to both sides of the connecting long pipe (410). The airflow then contacts the outside of the cleaning brush (504) and the working screw (401) respectively, cleaning the cleaning brush (504) and pre-treating the outside of the working screw (401). Step 3: The connecting ring plate (409) drives the ring plate (502) to rotate, which in turn drives the rotating ring bar (503) to rotate. When the rotating ring bar (503) rotates, it drives the ring slide bar (518) to rotate inside the mounting ring groove (517), improving the stability of the rotating ring bar (503) during rotation. The ring plate (502) drives the cleaning brush bar (504) to rotate, causing the cleaning brush bar (504) to contact and rub against the outside of the working screw (401), cleaning the working screw (401). The ring plate (502) drives the movable tube (506) and the movable rod (507) to move. The movable rod (507) drives the mounting ring frame (511) and the detection elastic hook (512) to slide inside the thread groove of the working screw (401). When the detection elastic hook (512) slides, it contacts the crack generated by the working screw (401), which will cause the detection elastic hook to move. When the hook (512) engages with the crack, it pulls the movable rod (507) so that it cannot move further. The movable tube (506) slides outside the movable slider (509) and the movable rod (507), and squeezes the compression airbag (508). The air inside the compression airbag (508) is squeezed into the movable rod (507). When the air is squeezed into the movable rod (507), air pressure is formed inside the movable rod (507), which pushes the movable sleeve (513) to move downward. When it moves, it squeezes the fixed spring (516). Later, the fixed spring (516) after being squeezed drives the movable sleeve (513) to move upward and reset. When the movable sleeve (513) moves to the bottom of the inner cavity of the movable rod (507), it squeezes the pressure sensor, triggers the alarm of the external remote control center, and disconnects the power supply of the single-phase motor (405) to stop the movement operation.
